The trio meets in winter 2004 when dutch bass player Joeri Hommerson who had just finished taping some pieces with X3 (Denny Seiwell drummer past member of Paul Mc.Carthney’s Wings and Chris Currel Guitarist past member of Michael Jackson band), decides to form an all European band (most of all Italian) signing Marco Maggiore on drums and Daniele Gregolin on guitar (session guitarist for many Italian pop stars).

They started working as a band on pieces already written in the past by Hommerson rearranging everything in new key tones giving birth to the Euro Groove Department.
In March 2005 they recoreded Optical Illusion in four days. Arranged by Euro Groove Department eleven original Hommerson's pieces were recorded, plus a very flashing version of Dizzy Gillespie’s “A Night in Tunisia”.
